EarthQuake MQB-1

The MQB-1 acts like a speaker for low-frequency vibrations rather than sound. You connect it to a separate amplifier, which receives the LFE (Low-Frequency Effects) signal from your receiver, allowing the transducer to physically vibrate your furniture in sync with the audio.

You need an amplifier capable of outputting between 20W and 500W at 8 Ohms. A dedicated subwoofer amplifier or a spare channel on a multi-channel amp usually works best, provided you can isolate the low-frequency signal.

The MQB-1 is designed for versatility, but it works best when mounted directly to a solid frame component of your seating, such as a wooden support beam. Avoid mounting it to loose cushions or fabric, as the vibrations need a rigid surface to transfer effectively.

The MQB-1 is designed to be silent. Because it translates sound into physical movement rather than audible waves, you should feel the impact in your seat without adding any distracting mechanical noise to your room.

Yes, this range is ideal for tactile feedback. Most of the 'feel' in explosions, engine rumbles, and impacts occurs below 50Hz, so this transducer is specifically tuned to capture those deep, physical sensations that standard speakers often miss.

For a single chair or loveseat, one MQB-1 is usually sufficient to provide a noticeable effect. If you have a larger sofa or multiple rows of seating, you may want to install one unit per seat to ensure everyone experiences the same level of immersion.
